This invention relates to box-making machines and particularly to machines for making wired. box parts.

It isan object of the invention to provide a unitized machine for stapling binding wires to box parts, severing the wires between box parts, bending the severed wires to form bights thereon, and driving the ends of the wires into the box parts to perpetuate the bights.

It is a further object of the invention to provide a machine of the character described with means for feeding the box parts through the machine continuously at substantially a uniform speed.

It is a further object of the invention to provide a machine of the character described in which the several mechanisms are automatically operated in accordance with the passage of the box parts through the machine.

It is a further object of the invention to provide a machine for forming a bight on a wire secured to a box part and driving the end of the wire into the box part to perpetuate the bight and in which means are provided for feeding automatically the box parts through the machine.

It is a further object to provide a machine of the character described which may be manufactured and operated economically and which is durable and efficient in operation.

Other objects will be in part obvious and in part pointed out hereinafter.

One illustrative embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 9 is a top plan view of a completed box blank.

Fig. 10 is a top plan view of a succession of wired box ends.

Fig. 11 is a top plan view of a completed box 15 end.

Referring to Fig. 8, the machine of this application is adapted (1) to receive and position in spaced relationship a succession of box blanks designated A, each blank consisting of four fold- 20 ably related sections designated respectively Al, A2, A3 and A4, (2) to feed the blanks A past staple forming and driving mechanism which staples binding wires W to the succession of box blanks, (3) to sever the binding wires W between 25 box blanks, (4) to bend the severed ends of the wires to form bights thereon, (5) to form a prong on each wire end (6) to drive the prongs into the box parts to perpetuate the bights, and (7) to clinch the prongs on the under side of the box 30 parts.

The box parts are fed continuously at substantially a uniform speed past the staple forming and driving mechanism and the mechanism for severing the wires and forming bights there- 35 on. A finished box blank is shown in Fig. 9.

The machine is also adapted to connect with wires a succession of box ends, as shown in Fig. 10, to sever the wires between box ends and to form bights thereon to produce the completed end 40 shown in Fig. 11.

Heretofore two separate machines have been used to produce the complete box blank shown in Fig. 9 or to produce the complete box end shown in Fig. 11, one machine being used to staple the binding wires to the box parts and. the other machine being used to sever the wires between box parts and form bights thereon.

A suitable machine for wiring the box parts is shown in my copending application Serial No. 37,107 filed August 21, 1935, reference to which is hereby made for a detailed description of the binding wire applying mechanism of the machine of this application and of the means for positioning and feeding the box parts past the staple forming and driving mechanism.

In the machine of said application Serial No. 37,107 the box parts are fed continuously at substantialiy a uniform speed, the staple forming and driving mechanism being constructed and arranged to operate at predetermined selected times to locate the staples at predetermined selected points in the work and to move with the work during staple driving operations, all as described in detail in said application.

A separate machine for severing the Wires between box parts and forming bights thereon is shown in my copending application Serial No. 40,240 filed September 12, 1935, reference to which is hereby made for a detailed description of the wire-manipulating elements of this application, which sever the wires between box parts, bend them to form bights and drive the wire ends into the box parts to perpetuate the bights.

In the machine of said application Serial No. 40,240 no means are provided for feeding automatically the box parts through the machine or for moving the Wire-manipulating elements with the box parts during a bight-forming operation. For this reason the binding wire applying machine and the bight-forming machine were necessarily operated independently of each other and as separate units, which retarded speed and efiicient production.

In the machine of this application mechanisms are provided for automatically feeding the box parts continuously through the binding Wire applying mechanism and the bight-forming mechanism, for moving the mechanism with the moving box parts during a bight-forming operation and at substantially the same rate of speed and for automatically controlling the operations of the several mechanisms in properly timed relation and in accordance with the passage of the box parts through the machine, with the result that the box parts are placed on continuously moving conveyors at the receiving end of the machine, pass through the machine without interruption and come out of. the delivery end of the machine as a finished product, thereby contributing to high speed mass production.

Referring to Fig. the box parts are positioned and fed on endless conveyor chains I, trained over idler sprocket wheels 2 on a shaft 3 supported by side frames .4 at one end of the stapling unit of the machine and trained over driven sprocket wheels 5 keyed to a shaft 6 journaled in side frames 4 at the other end of the stapling unit of the machine.

Shaft 6 is driven continuously at substantially a uniform speed through a gear 1 fast on shaft 6 and intermediate drive connections from a drive shaft 8, all as shown and described in said application Serial No. 37,107.

Referring to Fig. 2, as the wire-connected box blanks A leave the endless conveyor chains l of the stapling unit they are engaged at each side by endless belts I 0 which are driven continuously at substantially the same rate of speed as the conveyor chains l and carry the blanks through the bight-forming unit of the machine.

Belts I0 pass around driven pulleys II at the receiving end of the bight-forming unit and around idler pulleys i2 at the delivery end of the bight-forming unit.

As shown in Fig. 3, driven pulleys l I are fixed to a shaft [3 which rotates in bearings carried by a cross bar [4 supported by side frames 4 of the bight-forming stapling unit. Shafts l3 are rotated through a worm gear it? fast on shaft I3 which meshes with a gear it keyed to shaft 6 of the stapling unit. The size of the gears 55 and i6 and of the pulleys l i is such that the belts H] are driven substantially the same rate of speed as the conveyor chains I.

Shafts l3 and their bearings are adjustable on cross bar M to permit the belts Iii to be moved toward and from each other to accommodate box parts of. different Widths. Likewise, gears 16 are adjustable toward and from each other on shaft 6.

Idier pulleys l2 are rotatably mounted on shafts l"! carried by a bar i8 supported by extensions secured to frame IQ of the bight-forming unit. Shafts ii are adjustable on bar 18 to permit idler pulleys I? to be moved toward and from each other.

Frames i9 which support the bight-forming unit and frames 6 which support the stapling unit are definitely related to each other and preferably rigidly connected by plates. 20.

As shown in Fig. 2, the inner reach of each endless belt 50 is recessed by means of. rollers 2|, when a box blank having a wire adjacent each outer edge as there shown is being operated upon so that the belts will not interfere with the operation of the outside bight-forming units.

As shown in Fig. 4, the belts need not be recessed when box ends (having the wires set in a substantiai distance from each edge) are being operated upon. a

. Adjustably secured to cross bars 22 supported by extensions 23 of frames i9 are guide bars 24 which carry presser members 25 to bear against the inner faces of the inner reaches of the endless belts iil. Interposed between the guide bars 2%; and the pressers 25 at one side of the machine are a plurality of springs 25 which yieldingly press the pressers 25 against the belts l0 and thus press the belts it into gripping contact with the sides of the box blank to carry the box blank through the machine with the beits.

The box blanks in their passage through the night-forming unit are supported by rods 21 carried by cross frame members 28. The box parts are held against vertical movement by pgesser bars 29 carried by cross frame members 0 As shown in Fig. 3, the bight-forming instrurnentalities and the means for operating the same are carried by a frame 3| which is adapted to reciprocate horizontally on rollers 32 between guides 33 carried by frames l9. Frame 3! and the bigh"-forrning instrumentalities carried thereby are normally heid in the position shown in Fig. 3 by a spring 34 secured at one end to the frame 3! and at the other end to cross bar I 4. Vfhen a box part reaches the bight-forming mechanism the frame 3| is moved with the movmg box parts and at the same rate of speed by the mechanism now to be described.

Referring to gs- 2 and 3, there is mounted on the upper end of the continuously rotating vertical shaft 53 a clutch 35 of intermittent type and which is adapted to be clutched to the shaft 3 at selected times in the manner hereinafter described. Clutch 35 carries an arm 35 connected by a pin 31 to a rod 33, the other end of which is connected to a cross rod 39 carried by movable frame 38. The length of the arm 36 is such that rotation of shaft I3 will move frame 3i at the same rate of speed as conveyor chains and belts l0. 1

Referring to Fig. 6, clutch 35 is operated by lobes 48 carried by forked arms 4| secured to a frame 42 slidable horizontally on a table 43 carried by extensions 44 of frame l9. Frame 42 is positioned and guided on table 53 by guide blocks 45 secured to table 43.

Frame 62 is provided at its left hand end (Fig. 6) with a slot or recess 48 to receive the end of a rod ll, the other end of which (see Fig. 3) is connected to a link 5i which in turn is connected with a link 52 fixed to a rock shaft 49 journaled in frame 3i. When shaft 49 is rocked in a clockwise direction (Fig. 3) rod ll will be moved to the right, and its contact with the end of the slot or recess 55 in the frame 42 will move frame 42 carrying lobes 45 to the right, and this movement will throw clutch 35 into clutching engagement with shaft l3, as shown in Fig. 6. Thereupon, rod 33 will move frame 3! with the work and at the same rate of speed. Movement of frame 3! will continue just long enough to permit the bight-forming mechanisms to complete one operation, whereupon frame 42 and its lobes 48 will be returned. to initial position to disengage the clutch 35.

Frame 52 is returned to initial position through the action of cross frame member 30 carried by frame 3! which contacts a plunger 5! extending from a bracket 52 carried by frame 42. Surrounding plunger 5! is a spring 53 to insure positive return of the frame 42.

Rock shaft .9 is rocked to cause operation of clutch 35 by the action of the forward edge of the incoming box part which contacts and moves a trigger 54 pivotally mounted by a pin and slot connection 55 on an arm 56 secured to rod 39 (see Fig. 5). The lower end of trigger 54 lies in the path of travel of the incoming box part. The upper end of the trigger 54 is connected by a link 5'? to a link 58 secured to a rock shaft 59 journaled in brackets secured to frame 3!. Also secured to rock shaft 59 (as shown in Fig. 3) is a link til having a pin connection with the link (if, the other end of which is connected by a pin to the link 62 fast on rock shaft 49.

When the incoming box part engages and moves the lower end of trigger 56 to the left in Fig. 5, the upper end of the trigger 55 will move to the right, rocking shaft 59 in a clockwise direction and through links 60, El and 52, rocking shaft 49 also in a clockwise direction. This movement of shaft 49 will move rod 41 and frame 62 to the right to throw in clutch 35.

The same rocking movement of shaft 49 will throw a clutch buffer 63 from the position shown 1 in Fig. 3 to the position shown in Fig. 5 to clutch a drive pulley 5 2 to a drive shaft 55 which is journaled in frame 3! and actuates the bightforming mechanism carried by the frame 3|.

The night-forming mechanisms and their op- I oration are fully described in my copending application Serial No. 40,240 and need not be described in detail herein, it being sufficient to say that when pulley 55 is clutched to shaft 55 the bight-forming mechanisms will be thrown into operation for one complete cycle of operation. The clutch, designated 65 (see Fig. 5) is a one cycle clutch and automatically disengages after one complete cycle of operation.

Thus it will be seen that when the forward edge of the incoming box part strikes trigger 54, the movement of trigger 54 will automatically throw into operation clutch 35 to move frame 3| with the work and at the same time clutch pulley 56 to shaft 55 to cause the bight-forming mechanism to operate during its movement with the work. When the night-forming operation is completed, clutch 65 is disengaged in the manner described in my application Serial No. 40,240, clutch 35 is disengaged in the manner hereinbefore described, and frame 3i is returned to initial position through the action of spring 34.

Pulley G l may be operated by a belt Bl from a line shaft or in any other suitable manner.

The operation of the machine will be readily understood from the foregoing detailed description. The box parts are placed on the continuously moving chains l which feed the box parts beneath the stapling mechanism which staples the binding wires thereto. As the wired box parts leave the endless conveyor chains l they are engaged by the endless belts ill and moved continuously and without interruption through the bight-forming unit of the machine. As the forward edge of each unit of work strikes the trigger 54, the bight,-forming mechanisms are thrown into operation and are moved with the work while performing a bight-forming opera tion. After a bight-forming operation the bightforming mechanisms are returned to initial position while the continuously moving belts l8 carry the completed product out of the machine.

It will be noted that with the machine in operation the attendants simply place the box parts on the endless conveyors l at the receiving end of the machine and remove the completed prodnot from the belts ill at the delivery end of the machine, the several mechanisms being operated automatically in accordance with the passage of box parts through the machine.

It will be understood that the invention is not to be limited to the specific embodiment shown for purposes of illustration and that all of the inventive features need not be used conjointly as they may be used to advantage in various combinations as defined in the sub-joined claims.
